P_[ACTION]_priv#
This pattern tests the case when all participating processes perform concurrent I/O to different private files. This benchmark is particularly useful for the systems that allow completely independent I/O operations from different processes. The benchmark pattern is expected to show parallel scaling and obtain optimum results. See the basic definitions and a schematic view of the pattern below.
